Prevention Flashcards
What are the three strategies of preventative medicine?
Primary, secondary, and tertiary prevention levels
What is primary prevention?
Primary prevention is a strategy in which intervention occurs BEFORE health effects occur
What are some examples of primary prevention?
Vaccines, altering risky behaviors (tobacco use), banning substances known to be associated with a disease or health condition, education, wearing sun screen, using seat belts, washing hands
What is the goal of primary prevention?
Aims to prevent the disease from occurring, thus reducing both incidence and prevalence of disease
What is secondary prevention?
Screening to identify diseases in the earliest stages, before the onset of signs and symptoms
What are some examples of secondary prevention?
Screening tests, mammography, regular blood pressure testing, checking suspicious skin growths, modifications of work situations
When are secondary prevention measures used?
Used after the disease has occurred but before the person has an idea that something is wrong
What are the two goals of secondary prevention?
Find the disease and treat it early with the hope that it can be cured, thus decreasing morbidity associated with disease
Prevent the spread of transmittable diseases
What is tertiary prevention?
Managing disease post diagnosis to slow or stop disease progression
What are some examples of tertiary prevention?
Chemotherapy, rehabilitation, screening for complications, patient support groups, chronic pain management programs, stroke rehab programs, screening for renal issues in diabetics
Tertiary prevention is aimed at who?
Aimed at the person who already has the disease
What are the three goals of tertiary prevention?
Prevent damage and pain from disease and help with management
Slow disease progression
Address and possibly prevent potential complications associated with disease
What are the target activities of tertiary prevention?
Improve the care to patients with the disease and cure the disease so that patients are able to continue with their normal lives
Nutrition counseling to a group of well individuals is an example of what level of disease prevention?
Primary
The nurse starts a support group for the families of individuals with Parkinson’s Disease. This would be what level of disease prevention?
Tertiary
Explanation: helps family with managing patient
Which is the following is NOT an example of primary prevention?
- Treatment of STI
- Safety education
- Prevention of the initial occurrence of disease
- Education about health and safety habits
Treatment of STI
Which of the following is NOT an example of secondary prevention?
- Regular exams and screening tests to detect disease in its earliest stages
- Daily, low-dose aspirins and/or diet and exercise programs to prevent further heart attacks or strokes
- Immunization against infectious diseases
- Suitably modified work so injured or ill workers can return safely to their jobs
Immunization against infectious diseases
What is the USPSTF and what do they do?
United States Prevention Services Task Force - organization that provides recommendations for preventative services
What are the 5 grades of the USPSTF’s prevention recommendations?
A, B, C, D, and I
What is USPSTF’s grade A?
The USPSTF recommends the services and there is a high certainty that the net benefit is substantial. The service should be offered of provided.
What is the USPSTF’s grade B?
The USPSTF recommends the service. There is a high certainty that the net benefit is moderate or there is moderate certainty that the net benefit is moderate to substantial. The service should be offered or provided.
What is the USPSTF’s grade C?
The USPSTF recommends selectively offering or providing this service to individual patient based on professional judgment and patient preferences. There is at least moderate certainty that the net benefit is small. The service should be offered or provided for selected patients depending on individual circumstances.
What is the USPSTF’s grade D?
The USPSTF recommends against the service. There is moderate or high certainty that the service has no net benefit or that the harms outweigh the benefits. The service should be discouraged.
What is the USPSTF’s grade I?
The USPSTF concludes that the current evidence is insufficient to assess the balance of benefits and harms of the service. Evidence is lacking, of poor quality, or conflicting, and the balance of benefits and harms cannot be determined. If the service is offered, patients should understand the uncertainty about the balance of benefits and harms.
What is the natural history of disease?
Progression of disease in an individual over time
What are the steps of disease?
Stage of susceptibility, exposure, stage of subclinical disease, pathologic changes, onset of symptoms, stage of clinical disease, time of diagnosis, stage of recovery/disability/death
What stage of disease should primary prevention be used in?
Stage of susceptibility
What stage should secondary prevention be used in?
Stage of subclinical disease
What stage should tertiary prevention be used in?
Stage of clinical disease
